添加 JScrollpane 时框布局中的框未对齐

问题描述

我想使用 JTable 的一些功能创建一个简单的表格,但更容易设置样式,所以我在框布局中创建了几个框,一个用于标题,另一个用于包含单元格。当我将 JScrollPane 添加到单元格的框时,它缩进了标题框,现在不对齐了。

未对齐的框:

我尝试过 setAlignmentX 和 ComponentOrientation,但运气不佳。有人有什么想法吗?

public class GUIInventory extends JPanel
{
    Box headersBox = Box.createHorizontalBox();
    Box cellsBox = Box.createVerticalBox();
    JScrollPane scrollPane;
    ArrayList<Box> rows = new ArrayList<>();
    ArrayList<JLabel> cells = new ArrayList<>();
    JLabel[] headerLabels = new JLabel[4];
    String[] headerLabelNames = {"Name","Order Date","Order Number","Cost"};

    public GUIInventory()
    {
        this.setBackground(Color.WHITE);
        this.setLayout(new BoxLayout(this,BoxLayout.Y_AXIS));
        this.setAlignmentX(Component.LEFT_ALIGNMENT);

        Border outer = BorderFactory.createMatteBorder(0,1,Color.LIGHT_GRAY);
        Border inner = BorderFactory.createEmptyBorder(10,10,10);

        for(int i = 0; i < this.headerLabels.length; i++)
        {
            this.headerLabels[i] = new JLabel(this.headerLabelNames[i]);
            this.headerLabels[i].setBorder(BorderFactory.createCompoundBorder(outer,inner));
            this.headerLabels[i].setFont(new Font("Arial",Font.BOLD,16));
            this.headerLabels[i].setMaximumSize(new Dimension(200,(int) this.headerLabels[i].getPreferredSize().getHeight()));
            this.headerLabels[i].setAlignmentX(Component.LEFT_ALIGNMENT);
            this.headersBox.add(this.headerLabels[i]);
        }


        this.headersBox.setBorder(BorderFactory.createCompoundBorder(BorderFactory.createMatteBorder(1,Color.LIGHT_GRAY),BorderFactory.createMatteBorder(0,2,Color.BLACK)));
        this.headersBox.setAlignmentX(Component.LEFT_ALIGNMENT);
        this.headersBox.setBorder(BorderFactory.createLineBorder(Color.GREEN,2));

        this.cellsBox.setBorder(BorderFactory.createMatteBorder(1,Color.LIGHT_GRAY));
        this.cellsBox.setAlignmentX(Component.LEFT_ALIGNMENT);

        this.scrollPane = new JScrollPane(this.cellsBox);

        this.add(this.headersBox);
        this.add(this.scrollPane);
    }
